Thermostat Housings & Water Necks
Thermostat housings and water necks are essential components of an engine's cooling system, responsible for regulating the flow of coolant between the engine block and the radiator. The thermostat housing encloses the thermostat, which controls the temperature of the engine by opening and closing to allow coolant flow. Water necks, also known as thermostat housings, connect the radiator hose to the engine block and often include provisions for sensors or temperature gauges.
